EDTA anticoagulant tube purple cap, ethylenediamine tetraacetic acid (EDTA, molecular weight 292), and its salt are amino polycarboxylic acids that can effectively chelate calcium ions in blood samples. Cheating calcium or removing the calcium reaction site will block and terminate the endogenous or exogenous coagulation process to prevent the coagulation of blood samples.What is an EDTA Tube for Blood Collection?EDTA tubes are specialized blood collection tubes that contain ethylenediaminetetraacetic acid (EDTA) as an anticoagulant. This compound is crucial in preventing blood from clotting, making it essential for various laboratory tests. The primary function of EDTA is to bind calcium ions in the blood, which are necessary for the coagulation process. By chelating these ions, EDTA effectively inhibits the coagulation cascade, allowing for accurate analysis of blood components.The Use of Different Vacuum EDTA Blood Collection TubeVolume/mlSize/mmAdditiveSeparatorMaterialCap ColorClosure2ml13X75EDTA K2 / EDTA K3/PET/GLASSPurple Cap TubeSafety Cap Rubber or Rubber Stopper3ml13X75EDTA K2 / EDTA K3/4ml13X75EDTA K2 / EDTA K3/5ml13X75EDTA K2 / EDTA K3/6ml13X100EDTA K2 / EDTA K3/7ml13X100EDTA K2 / EDTA K3/8ml16X100EDTA K2 / EDTA K3/9ml16X100EDTA K2 / EDTA K3/10ml16X100EDTA K2 / EDTA K3/If You Need a Customized customized Blood collection tube, Please Contact Us What are the different types of EDTA tubes?EDTA tubes from Sinymedical are available in three versions: K2E K2EDTA, K2E K2EDTA Separator, and K3E K3 EDTA. The additive potassium EDTA (ethylenediaminetetraacetic acid) contained in the tube interferes with calcium and thus blocks the coagulation cascade.What is the volume of an EDTA tube sample?Tubes with various draw volumes are available (2.0 mL, 3.0 mL, 5.0 mL, and 0.75 mL microvettes).The volume of an EDTA tube sample typically ranges between 2 and 10 milliliters. This range allows for flexibility in accommodating various specimen sizes and ensures that an adequate amount of sample is collected for diagnostic procedures. The precise volume may vary based on the specific EDTA tube model or manufacturer.
